A patch to fix the problem
Palapeli sometimes crashes when using piece holders. What seems to happen is
that two pieces in different scenes/views are merged, and the code trying to
update the piece list for one of these scenes fails to remove the piece because
it's not on the list. The piece then gets deleted (through a deleteLater call),
but it's still in the list for another scene, and we get a use-after-free
scenario.
I'm attaching a patch which seems to fix it - I've been unable to reproduce
crashes after this.
